Fairly new group of players and GM. We are playing a Champions game and I'm making and aquatic themed hero. In the powers book there is a power called crashing wave that makes a 32m line perpendicular to my character. I was wondering if when using the power I could adjust that size depending on the situation so i don't hit an ally or something? If someone has an answer or can point me to one of the rule books explaining it I would appreciate it. thank you
